摘要: 为明确光照条件对烤烟生长和品质的影响,在四川中海拔烟区通过对盆栽烤烟全生育期进行人工遮光,设置5个光照水平即自然光(T1)、60%自然光(T2)、40%自然光(T3)、20%自然光(T4)和10%自然光(T5),比较分析了不同光照条件下烤烟叶片理化成分和致香物质含量等指标的差异。结果表明:随着光照条件从自然光逐级减至10%,烤烟叶片表皮厚度、栅栏组织厚度和海绵组织厚度逐渐降低,烤后烟叶单叶重、厚度、叶质重逐渐降低,叶片含梗率逐渐增加,对叶片平衡含水率的影响不显著;烤后烟叶总糖和还原糖含量逐渐降低,总氮、烟碱、钾和氯含量有不同程度的增加;叶黄素、β-胡萝卜素、类胡萝卜素总量、部分中性致香成分含量和总量呈增加趋势。研究结果可为中高海拔烟区烟草种植布局和特色烟叶形成机理提供理论依据。

Abstract: In order to study the relationship between light and quality of tobacco leaf, the potculture experiments were conducted in intermediate altitude area of Sichuan province. Shadingcontrolled experiment were conducted to achieve five different irradiances of 100%(T1),60%(T2),40%(T3),20%(T4)and 10% (T5)of full sunlight, the differences of leaf structure and the physics and chemistry characteristic and aromatic components of fluecured tobacco under different light conditions were studied. The results indicated that tobacco leaves thickness, rate of palisade tissue and spongy tissue thickness of leaves palisade tissue and spongy tissue reduced when light intensity decreased. The per leaf weight,thickness,weight per unit leaf area,leaf density and sugar content of flue cured tobacco were decreased under low light intensity. However,the content of stem ratio,nicotine,total nitrogen,potassium,chlorine,lutein,carotenoid and neutral aroma constituent increased. The research results provided a theoretical basis for tobacco planting in high and intermediate altitude area and the mechanism of formation of tobacco characteristics.
